Final answer:
A PA can prescribe non-benzodiazepine Schedule IV medications up to a 30-day supply, subject to state laws and regulations.
Step-by-step explanation:
A Physician Assistant (PA) may prescribe Schedule IV (CIV) medications (non-benzodiazepines) up to a 30-day supply unless otherwise indicated or restricted by state laws and regulations. Schedule IV medications are controlled substances that have a lower potential for abuse relative to substances in Schedule III. It is important to remember that prescribing authority can vary by state and over time, so it's essential to consult local regulations.
